Intellectual property rights have to be balanced against Fair Use, as well as against practical reality. This means the balance between IP protection and Fair Use has to take into account how much IP protection ( particularly, how much financial protection ) will *actually* be achieved, not some pie-in-the-sky wish for zero copyright violation. If that amount of actual expected protection is dwarfed by the level of Fair Use infringement, than the DRM in question shouldn't be sanctioned.
